    摘要: A method of fabricating a complementary metal oxide semiconductor (CMOS) device, wherein the method comprises forming a first well region in a semiconductor substrate for accommodation of a first type semiconductor device; forming a second well region in the semiconductor substrate for accommodation of a second type semiconductor device; shielding the first type semiconductor device with a mask; depositing a first metal layer over the second type semiconductor device; performing a first salicide formation on the second type semiconductor device; removing the mask; depositing a second metal layer over the first and second type semiconductor devices; and performing a second salicide formation on the first type semiconductor device. The method requires only one pattern level and it eliminates pattern overlay as it also simplifies the processes to form different silicide material over different devices.

    摘要: A MOSFET structure and method of forming is described. The method includes forming a metal-containing layer that is thick enough to fully convert the semiconductor gate stack to a semiconductor metal alloy in a first MOSFET type region but only thick enough to partially convert the semiconductor gate stack to a semiconductor metal alloy in a second MOSFET type region. In one embodiment, the gate stack in a first MOSFET region is recessed prior to forming the metal-containing layer so that the height of the first MOSFET semiconductor stack is less than the height of the second MOSFET semiconductor stack. In another embodiment, the metal-containing layer is thinned over one MOSFET region relative to the other MOSFET region prior to the conversion process.
